Answer:
Secondary voltage on second transformer is 200 volt.
Explanation:
It is given two transformer
Let us consider first transformer.
Number of turns in primary
Numb er of turns in secondary
Now consider second transformer
Number of turns in primary
Number of turns in secondary
Now it is given that same voltage of 50 volt is applied to primary of both the transformer.
For second transformer
So secondary voltage on second transformer is 200 volt
To solve this problem it is necessary to apply the concepts related to Malus' law. Malus' law indicates that the intensity of a linearly polarized ray of light that passes through a perfect analyzer with a vertical optical axis is equivalent to:
Indicates the intensity of the light before passing through the Polarizer,
I = The resulting intensity, and
= Indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
There is 3 polarizer, then
For the exit of the first polarizer we have that the intensity is,
For the third polarizer then we have,
Replacing with the first equation,
Therefore the transmitted intensity now is of the initial intensity.
